I have to ask a question that's NOT speaker-related:

I see you have an XM receiver hooked up to the system. How does the sound REALLY compare to CDs? Listening through car speakers in Best Buy I'm sure does not do the service justice, but I really think I'd only be interested if it (or Sirius) is really CD quality or extremely close....especially now that the resolution of the Axioms will show an inferior source!

(Oooh! I DID make it about speakers!)
